BELT-FASTENER.

SPECIFICATION forming part of Letters Patent N0. 771,279, dated October4, 1904.

Application filed July 3, 1903. Serial No. 164,212. (No model.)

To all whom it may concern:

Be it known that I, EUCHARISTE Smors, a citizen of the United States,residing at Denver, county of Denver, and State of Colorado, haveinvented certain new and useful Improvements in Belt-Fasteners, ofwhichthe following is a specification.

My invention relates to belt-fasteners.

' The object of the present invention is to provide a belt-fastener ofimproved construction whereby adjustment to compensate for taking up orletting out of the belt can be made with ease and rapidity.

Another object is the provision of an improved and novel belt-fastenerof the hinged type which will have adouble grip or clenching action ofthe belt, and thereby give greater security of connection.

Having the foregoing objects in view, the invention consists of certainimproved features, hereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a perspective view showing thebelt in dotted lines and the improved fastener in position thereon. Fig.2 is adetail of the blank from which one part of the fastener is formed;Fig. 3, a detail of the blank from which the other part of the fasteneris formed; Fig. 4, a detail showing how one part of the fastener can bemodified; Fig. 5, a detail of the fastening for the pintle, and Figs. 6and 7 details of parts of a modified construction.

The belt-fastener is made in two parts 1 and 2, similar in all respects,except that 1 when bent into shape has three pintle-loops 3, and 2 hastwo pintle-loops 4. A greater or lesser number of pintle-loops may beused on the parts 1 and 2, provided they correspond. A removable pintle5 extends through all the pintle-loops, and thus hinges the two parts 1and 2 of the fastener together, making a joint which suitably flexeswhen the belt is running around the pulley. Each part 1 or 2 has twoplates 6 and 7, disposed on opposite sides of the belt 8; but the plate6 is considerably narrower than plate 7. The plate 6 hasclenching-prongs 9 disposed at suitable intervals, which are designed tobe passed through the belt and entered through correspondingly-spacedopenings 10 in plate 7 and clenched against the latter, the tips beingturned in opposite directions in alternation when being clenched. Theplate 7 has clenchingprongs 11 on its outer edge, which are preferablypositioned out of alinement with the prongs 9, and the prongs 11 aredesigned to be passed through the belt and their tips clenched on theopposite side thereof, as shown at 12.

It will be understood that the parts 1 and 2 are each made in a singlestamping, the blanks being shown in Figs. 2 and 3 from somesuitably-bendable sheet metal.

If the belt is to be disconnected, the pintle 5 can be pulled out,whereupon the parts 1 and 2 separate. If the belt needs shortening, theprongs on either of the parts 1 or 2 can be disengaged, the desiredportion of the belt out off, and the said part of the fastener fastenedto the belt again and the pintle inserted. To lengthen the belt, anadditional section of belting can be provided at its ends with the twoparts of the fastener and the said parts then connected to the parts ofthe fastener on the belt proper.

If preferred, the parts of the fastener can be of the form shown in Fig.4, where rivets 13 permanently fasten the plates to the belt. As shownin Figs. 6 and 7, both rivets and prongs can be used, in which case theplates 6 are omitted, leaving the pintle-loops 17 and 18 only. In eachinstance I notch or groove the pintle at 14 and surround it by a wire15. whose twisted ends are let through a slot 16 in the plate, thuspreventing detachment of the pintle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with a belt, fasteners secured to the ends thereofeach comprising plates positioned on the opposite faces of the beltends, one of said plates provided with openings and having prongsadapted to pass through the belt and besecured, the other plate havingprongs adapted to pass through the belt and the openings in thefirst-named plate and be there secured, and a grooved pintle removablysecuring said fasteners together.

2 In combination with a belt, fasteners securing the fasteners together,and independcured to the ends thereof each comprising ently-movablemeans engaging the pintle and plates positioned on the opposite faces ofthe said slot and adapted to normally hold said pinbelt ends, one ofsaid plates provided with tle in engagement with the fasteners.
